TRUSS-HOOP.

SPECIFICATION forming part of Letters Patent No. 437,645, dated September 30, 1890.

Application filed July 19, 1889. ,Serial No. 317,972. (No model.)

To all whom it may concern:

Be it known that I, DAVID DELANO, a citi- 4 zen of the United States, residing at Baldfull, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, in which- Figure l is a plan view of my improved truss-hoop; Fig. 2, a vertical transverse section taken on line X X, Fig. l; Fig. 3, an eX- terior edge View, and Figs. 4 and 5 are details.

Similar letters and figures of reference indicate corresponding parts throughout the several views. My invention relates to that class of devices employed in cooperin g commonlytermed truss-hoops, and which in the process of manufacturing barrels, casks, &c., are placed around a barrel to strain the staves into proper position, compressing them circumferentially toward the chine, and thus leaving the bulge at the middle portion thereof.

In the commonly-usedforms of the trusshoops the jar, blows, and particularly the great outward strain or pressure to which they are subjected incident to the constructing of a barrel, tends to readily and quickly weaken and rupture the encircling trusshoops, and consequently necessitating frequent renewals of same or new ones in lieu erative and staying qualities for a lengthyl period, and capable of being manufactured' at small cost; and to that end my invention consists in securing to the top of the coinpressing-hoop an extra hoop for receiving the impingement of the coopers tool, and thus relieving the compressing-hoop from the wear and tear incident to the impingement ofthe aforesaid tool, all as hereinafter more-fullyl described, and specifically set forth in the claims. l

l represents my improved truss-hoop, which is composed of two stout flat hoops A A', of Wood, each of which hoops is complete and self-sustaining. Said 'hoops are nearly or quite of the same circumference externally, and are placed one upon the other. The lower hoop A, I designate the compressinghoop, inasmuch as its sole function is to press on the exterior of the staves during the operation of compressing circumterentially the end of the barrel or cask in process of construction. The extra superimposed hoop A, I term the pounding-hoop, for the reason that said hoop receives the impingement of the coopers tool in the process of tightening the hoop on the aforesaid barrel or cask, and thus the lower compressing-hoop is relieved from the wear and tear incident to the impingement of the coopers tool in pounding the truss-hoop down on the barrel or cask. The-inner side of the pounding-hoop I bevel inward from the bottom to the top similar to the usual bevel of the subjacent compressinghoop, and thus enlarge the top surface of the pounding-hoop to afford more extensive and consequently more durable bearings for the pounding-tool. Said hoops are secured firmly together by rivets a, disposed at intervals circumferentially along their bodies and inserted vertically through both contracting hoop-bodies and securely binding them together. Each of the hoopsAA,I make complete and self-sustaining by forming the same with overlapping interlocking ends, as shown at c in Figs. 2 and 3 of the drawings. This lock-joint connection of the meeting ends of the hoop portion A is situated diametrically opposite that of the hoop portion A, whereby the joint ot' the pounding-hoop is sustained by the solid central portion of the subjacent compressing-hoop, and, vice versa, the joint of the latter hoop is protected by the solid central portion of the top hoop, and thus the truss-hoop is so strengthened as to enable it to effectually resist the strain incident to driving the same on the cask or barrel, and a far too I greater degree of strength is imparted to the combined hoops than there would be were the meeting ends of the hoop portions A A secured together at or about the same point.

C C are stays vertically encompassing at bottom, outer edge, and top of that portion of the truss-hoop Whereat is formed the lockjoints c, through which pass vertical rivets d, that serve to bind or clamp the locked ends of the respective hoop portions in close and unyielding embrace. Said stay C comprises a vertical edge portion and top and bottom horizontal portions, and may be formed of an integral piece of metal, as shown in Fig. 4 of the drawings, or of independent parts connected to the hoop portions and to each other by rivets, as illustrated in Fig. 5 of the drawings.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1'. The improved truss-hoop composed of a hoop for compressing the barrel circumfer` entially and an eXtra hoop secured to the top the other hoop, substantially as described and shown.

In testimony whereof I affix mysignature, in.

presence of two Witnesses, this lith day of July, 1889.
